Devices are already known for the wet treatment, removal of moisture from and drying of balls of thread or the like to which the several agents used for treatment are forced through the material successively by centrifugal action.

In the known devices there are several containers arranged one above the other for receiving the treating agents, the topmost of these con-' tainers being used as a common feed chamber for all the agents with. which the yarnis treated. The defect of this arrangement is that transmission to the balls of thread was only effected by the suction of the worm arranged in the interior of the spindles. The quantity of agent which is driven through the material is controlled mainly by'the difference in pressure between the interiors of the spindles and the outside -of the balls.

It has also been proposed to rotate balls of thread in a closed container filled 'with liquor and to effect a rotating movement of the liquor in the container by a centrifugal wheel arranged in the bottom. The effect of a revolving device of this kind is very slight because the action of the centrifugal force can only be developed to a very slight extent in the ball of thread.

These deficiencies are according to the invention obviated inasmuch as the several containers for receiving the balls, which containers are shut oil? from the outside air, are connected up in such a way to the corresponding liquor delivering agencies, in particular blade wheels or the like, that any collection of liquor outside the material cannot occur.

In order at the same time to provide for continuity of operation a distributing means is provided between the containers and the centrifugal device, which means at the same time regulates or controls the admission and discharge.

On the drawings a constructional form of the invention is illustrated, in which Figure l is a diagram of the arrangement of a centrifugal dyeing device on a container consisting of three chambers. Fig. 2 is a plan of the dyeing machine for twelve centrifugal dyeing devices. Fig. 3 is a longitudinal section through a centrifugal dyeing device. Fig. 4 is a longitudinal section through a. distributing agency. Fig. 5 is a section through the line 5-5 of Fig. 4 and. Fig. 6 is a section through the line 6-6 of Fig. 4. Fig. '7 is asection of a modified form of thecentrifugal dyeing device. Fig. 8 is a section through the line 8-8 of Fig. 7.

The machine consists of the container l0, which contains three chambers, H, l2 and l3,

which can in any desired way, preferably by jacket heating, by electricity or steam, be raised to the desired temperature. chamber H there is the dyeing. liquor, in the chamber l2 the washing liquid, and the top chamber l3 contains'an air heater of any desired kind. a

On the outside wall of the container 12 there are arranged for example 12 centrifugal dyeing devices each of which is fixed by means of a base 44 to the container Ill. The base l4 has double In the bottom' ball-bearings l5 whichserves as the mounting for a hollow-shaft l6. At the'top end of the bottom shaft there is a screw pin I! on which a bobbin spindle l8 can be screwed. This bobbin spindle I8 is hollow and hason the outside longitudinal grooves H! which communicate with the bore by apertures 20 of any form. Over this spindle IS the bobbin 2| is skewered, being shaped or formed on a sleeve 22 provided with perforations.

The hollow shaft a blade wheel 23, the blades of which open into a spiral housing 24, which is mounted on the base M. A perforated casing 25 is fixed by the flange 26 to the blade wheel 23. In the casing 25 a glass jacket is fixed by a screw ring 28, which is securely held in its position with the aid of the packlngs 29. The casing 25 participates in the rotation of the blade wheel 23 and conseque' tly in the rotation .of the hollow shaft l6.

l6 also hasat its upper end At the upper end the casing 25 is shut off by a cover 30, which can be fixed to the casing 25 by a bayonet joint 3|. The packing between the casing 25v and the cover 30 is a rubber ring 32.

On the cover 30 a pin 33 is fixed tothe mid die, on which a conical head 34 can slide. This head 34 is under the action of the spring 35, and in its hollow it has a packing 36 by which it can press down on the bobbin 2l.- This-head not only comes to lie close against the bobbin 2| but also presses them firmly on the spindle l8. At the bottom end of the hollow shaft IS a ring 31 is screwed which serves bearing l5, and has clutches 38 on its under face. with the clutches 38-there engage the clutches 39 of a hollow shaft 40 of the motor 4, which is fixed to the container by means of the base a. The electric motor 4| efiects the rotation of the hollow shaft l6, and thereby of the blade wheel 23 the casing 25, and the bobbin 2!.

Through the hollow shaft 40 of the motor and ta. secure the ball the hollow shaft 16 a stationary pipe 42 passes,

die 43 is fixed which conveys the media in the tube 42 upwards to the hollow bobbin spindle I8.

The bottom end of the pipe 42' is fixed to a short pipe 44 of a distributing agency (Fig 4-6). This distributing agency is fixed in any desired way to the container l0.

The distributing agency consists of the casing 45 in which a cone 46 is 'turnable, which, by means of a centre partition 41 forms two chambers 48 and 49 in the distributing agency. The cone 46 has a shaft 50, which is closely guided in the casing cover 5| and carries on the outer end an indicator disc 52, with' -handle 53. A spring 54 tends to press the cone 46 on its seat. The casing 45 has three short pipes 55, 56, 51, staggered at an angle of 120", through which the corresponding media can pass from their containers I], I2 and 3 into the chamber 48. To the chamber 49 there are also connected up three short pipes 58, 59, 69, the first two of which also lead to the containers l2, while 60 only carries a pipe leading into the open air. In the chamber 49 there likewise ends a short pipe 6| which is in communication with the outlet of the spiral casing 24. The cone 46 has two passage openings 62 and 63, the former of which leads into the chamber 48 and is of just the right size in order successively to expose the bore of the pipes 55-51. The opening 63 lies on the same line of the jacket as the opening 62, but is elongated so that it still'keeps the bores of the pipes 5868 open, when the bores of the pipes 5551 are closed. The object of this arrangement is to permit of the outfiowof the excess of media still present in the centrifugal dyeing device, even when th inflow is already shut oif.

The way in which the device, according to Figs. 1-6 operates, is as follows: After starting the centrifugal dyeing device the distributing agency is put into the position Figs. 4-6.

- The screw spindle 43 then exerts suction on the liquid in the chamber H, the latter being drawn through the chamber 48. The liquid rises up in the pipes 42, and reaches the hollow bobbin spindle. From here the. liquid is forced through the bobbin body 2| by the feed pressure and the centrifugal action. As at the same time a vacuum is created in the casing'25 by the blade wheel 23, the liquid will be able to pass through more easily. The liquid which gets into the casing runs into the blade wheel, and is conveyed by the latter tothe pipe 8| of the distributing agency from where again through the-pipe 58 it reaches the container When the: bobbin 2| has been sufiiciently treated the cone 46 is turned to such an extent that the pipe 55 isshut off. The inflow is thus stopped. The liquid present in the centrifugal dyeing device is, however, then still able to fiowout through the opening 63 which is still open and the pipe 58 until it is quite emptied out. I

:Th'ereupon the cone 46 is turned till the openings 62 and. 63 lie over the pipes 56 and 59. The container I2 is now connected up to the distributing agency so that now the same operations as described above are repeated with the liquid present in the container I2.

0n the termination of this process the tap is again turned and the openings 62 and 63 brought over the pipes51 and 68. The centrifugal dyeing device is now connected up to the air heater 3, so that the bobbin 2| is now dried by the hot air passing through. In order, after the completion of all the processes, to conduct all liquids back into the containers, which should stand up to the volume distributing agency there is provided a small orifice 64, for admission of air, which alspindle takes place by means of the worm 43 arranged in the spindle. In many cases, however, the pressure produced by a worm is not suifi-. cient to drive the media through the material. Furthermore, it is not always desirable to bore through the shaft of the driving motor. In addition, it is necessary to empty completely all parts of the medium conveying device, in order to prevent the media getting'mixed up in the device on changing over from one medium to the other. This is particularly necessary when changing over from the moistening liquid to the dye.

These defects are avoided in the fullest measure in the arrangement according to Figs. '7 and 8. The spindle |8 with the bobbin 2| has the same form as in the arrangement according to Fig. 1. Rotation of the spindle 8 is effected by a shaft 66, which runs in two ball bearings 61 and 68 of a housing 69 which can be fixed to the container ID by the base 10 in the same as according to Figs. 1-3. The drive of the shaft 66 is by a normal'vertical motor 1| through the medium of a coupling 12. housing 69 a centrifugal pump housing 13 in which the rotor impeller wheel 14 which is fixed on the shaft 66 by groove and tongue, works. The casing 15 is closed above by a channelled cover 13a, in which a channel conveys the medium transmitted by the rotor to the shaft 66. Above the top of the channelled cover the shaft is provided with a screw thread 15, of several turns, on which a second rotor 16 is fixed, for example by shrinking on. From the.channel1ed cover 13: a passage 11 leads to the screw thread 15. Inside the wheel 16 a passage channel 18 abuts on the screw thread 15, and leads to the interior of the spindle |8. The rotor impeller wheel 16 runs similarly as in Fig. 3 in a casing19 which can be connected with the casing 13 and the channelled cover 130. by screws or'the like.

The casing 19 has a perforated bearer 8|, the' walls of which are formed by a glass jacket 82.

Above the bearing This bearer 8| and the glass jacket82 however,

remain stationary. The bearing 8| is shut off above by a cover 83 which can be secured to the bearer 8| by abayonet joint or by other suitable method of fastening.

As in the present case, the cover 83 does not share in the rotation of the bobbin, the head 34 with its elastic springing, is tumable in the cover 83 on a ball bearing 84. In order to be able to connect up the bottom centrifugal pump to the containers I2 and I3, the suction chamber 85 has three connecting pipes 86. .The top casing 19 also has three connecting pipes 81. The pipes 86 and 81 are arranged vertically above one another so that two of them ata time can always be connected up to pipes 88 and 89 of a cock body 90. In the cock body 99, a cone 9|, is fitted turnable by a hand wheel 92, which cone by a wall 93 divides off two chambers '94 and 95 in the body 98. The bottom chamber 94 communicates with a pipe 96 to which a'pip'e 91 can be connected up. This pipe 91 leads each time to the several containers l2 and I3 respectively. This pipe 91 forms the suction pipe of the centrifugal pump,

media are connected up to the latter near the bottom. In each case, however, the connecting pipe 96 must lie higher than the highest level of liquid in one of the containers ll, l2 orlfi. 0n the other hand, the tube 91 of the cock which leads to the air heater, is connected up to the upper end of the air heater, and it is immaterial whether the air heater is high or low. The top chamber 95 of each cock has an outlet aperture 99 which communicates with a short pipe not shown, which in its turn is connected by a pipe with the same container iii, H or l2, as the pipes 91. The pipes coming from the outlet opening 98, however, and above the liquid in the correspondingcontainers. In "the case of the cock which only'contains hot air, a connection for conveying away is not necessary, but a pipe leading into the open air may preferably be provided, as shown in Fig. 1, pipe line 60.

The openings 99 and I08, which act on the pipes 86, and 8?, and also the opening 8M, which acts on the outlet opening 98, are so designed that theoutlet 98 is still almost fully open when I the opening 99 is already nearly closed. Shortly the rotor impeller ll draws air but no liquid. The liquid in circulation from time to time in the centrifugal dyeing device no longer gains admission and is gradually expelled. Only now is the cock in question completely closed, and following thereon the next cockis opened. In what way the media pass through the centritugal dyeing device is shown by the arrows.
